1. The shell of a crustacean is primarily made of Calcium carbonate. As ocean acidification becomes more of a problem in our climate, crustaceans are suffering from habitat destruction.
H2O (l) + HCO3- ←→ H3O+ (aq) + CO32- (aq) Ka = 4.7 x 10-11
You take a 1.0-Liter sample of ocean water and determine that there are 8.127 x 1017 molecules of HCO3-. What will be the pH of the ocean based on this sample?
2. Sodium Nitrate mixes with potassium carbonate in a solution of water. Write out the ionic equation.
3. Sulfurous acid is added to water. Write out the ionic equation.
